3. A 45,000 kg rocket is at rest lying on the ground pointing westward. The rocket engines are touching a 2,300 kg mobile cart that is also at rest pointing in the other direction. When the rocket engines fire an impulse is
produced from 840,000 N of force for a period of 1.3 seconds.
a. Solve for the impulse (J = Fxt). This is also the change in momentum.
b. What is the final speed of the rocket? [ Ap = m(vp-v) ]
C. What is the final speed of the cart? (both the rocket and the cart have the same change in momentum)

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
